Description

Technical Field

[0001] This invention belongs to the field of bridge crane track handling tools. Background Technology

[0002] The overhead crane tracks in the underground powerhouse of pumped storage power stations are very long. Taking the Jinyun Pumped Storage Power Station as an example, the total length of the overhead crane tracks exceeds 200 meters. The tracks are composed of multiple sections of I-shaped rails spliced ​​together. Each individual rail is very long, and due to space limitations in the underground powerhouse, very long vehicles cannot pass through, making it impossible to load and transport the tracks. Cranes are shorter and can travel within the underground powerhouse space, but due to the limited height of the underground space, the crane booms are difficult to lift, making them unsuitable for suspending and transporting the tracks. Currently, the tracks are manually dragged to the designated location. The tracks are heavy, requiring multiple people to work together to move them, demanding a large number of operators and resulting in high labor intensity. Summary of the Invention

[0003] The purpose of this invention is to provide a bridge crane track handling tool. This invention has the advantages of requiring fewer operators, reducing labor intensity, ease of operation, and wide applicability.

[0004] The technical solution of the present invention: a bridge crane track transport tool, including a base plate, a plurality of casters on the bottom surface of the base plate, a gantry frame on the top surface of the base plate, and a hoist on the top of the gantry frame.

[0005] In the aforementioned bridge crane track transport tool, the multiple casters are located at the edge of the base plate, and the casters are equipped with locking devices.

[0006] In the aforementioned bridge crane track handling tool, a first rotating shaft is provided below the hoist, a second rotating shaft is provided behind the first rotating shaft, and a third rotating shaft is provided below the rear of the second rotating shaft. The lifting end of the hoist passes around the first rotating shaft, the second rotating shaft, and the third rotating shaft in sequence. The lifting end of the hoist is provided with a tow device for connecting to the track.

[0007] In the aforementioned bridge crane track transport tool, the tower includes a tow plate, the front side of the tow plate is bent upward to form a guide plate, the rear side of the guide plate is provided with an end plate fixed to the tow plate, the rear side of the end plate is provided with a slide groove, two sliders are provided in the slide groove, and a switch magnetic seat is provided on the slider, with the adsorption surface of the switch magnetic seat facing inward.

[0008] In the aforementioned bridge crane track handling tool, a reinforcing rib is provided between the guide plate and the end plate, and the lifting end of the hoist is connected to the reinforcing rib.

[0009] In the aforementioned bridge crane track handling tool, the lifting end of the hoist is horizontally connected to a reinforcing rib after passing around the third rotating shaft.

[0010] In the aforementioned bridge crane track transport tool, the front side of the base plate is provided with an L-shaped rotating plate. The horizontal part of the rotating plate extends backward and has multiple rivets at the bottom of the rear end. The vertical part of the rotating plate is rotatably connected to the base plate, and the first rotating shaft is rotatably connected to the upper end of the rotating plate.

[0011] In the aforementioned bridge crane track transport tool, a spring is provided between the rotating plate and the base plate.

[0012] In the aforementioned bridge crane track transport tool, the gantry frame is located near the front side of the base plate, and a support beam is provided between the gantry frame and the base plate.

[0013] Compared with existing technologies, this invention has a compact structure and small size, making it suitable for movement in underground factory sites and applicable to track-driven transportation. This invention uses the power of a hoist to move the track. Because the hoist has a torque amplification function, the track can be easily moved by a single operator, reducing the number of operators required and minimizing labor intensity.

[0014] By installing rollers on the base plate, the tool can be moved easily, further reducing labor intensity. By selecting rollers with locking devices, the tool will not slide on uneven ground when not in use, ensuring on-site safety.

[0015] Increasing the height of the hoist by using a gantry crane makes it easier for workers to operate; pulling down the cable on the hoist also facilitates operation.

[0016] By setting the first pivot below the hoist, the slings near the hoist extend downwards and remain relatively vertical, meeting the conditions for "lifting" and making the hoist usable. Then, by using the second and third pivots, the direction of the slings is changed, transforming the hoist's lifting force into a horizontal tension force, which drags the track forward.

[0017] By connecting the first rotating shaft to the rotating plate, the tension of the slings causes the first rotating shaft to move during the dragging of the track, driving the rotating plate to rotate. This causes the spikes on the rotating plate to automatically drive into the ground, establishing a reliable connection and providing a reliable anchor point for the dragging of the track. When the dragging track is being laid, the spikes do not contact the ground due to the action of the springs, ensuring smooth tool movement and further facilitating worker operation.

[0018] In the tow unit, two switch magnetic bases are used to connect the track, which makes it easy to connect and disconnect the tow unit from the track, further facilitating worker operation. The two switch magnetic bases can also move relative to each other to form gaps of different widths, adapting to the web thickness of different track specifications. This allows the tow unit to be connected to tracks of various specifications, making it widely applicable.

[0019] In summary, the present invention has the advantages of low operator requirements, reduced labor intensity for workers, ease of operation, and wide applicability. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example. A bridge crane track transport tool, such as Figure 1 As shown, the system includes a base plate 1, on which four casters 2 are located at the four corners. Each caster 2 has a locking device 5. Casters 2 with built-in locking devices 5 are existing technology; when the locking device 5 is open, the caster 2 can roll, and when the locking device 5 is closed, the caster 2 cannot roll. A gantry frame 3 is mounted on the top surface of the base plate 1, and a hoist 4 is mounted on top of the gantry frame 3. The hoist 4 is a manual hoist, and its height from the ground is 1.5-2 meters.

[0025] The hoist 4 has a first rotating shaft 6 located below it, a second rotating shaft 7 located behind it, and a third rotating shaft 8 located below and behind the second rotating shaft 7. The lifting end of the hoist 4 passes sequentially around the first rotating shaft 6, the second rotating shaft 7, and the third rotating shaft 8. The lifting end of the hoist 4 is equipped with a dragger for connecting to the track. The second rotating shaft 7 and the third rotating shaft 8 are both rotatably connected to the base plate 1 through corresponding brackets.

[0026] The tow device includes a tow plate 9, the front side of the tow plate 9 is bent upward to form a guide plate 10, the rear side of the guide plate 10 is provided with an end plate 11 fixed to the tow plate 9, the rear side of the end plate 11 is provided with a slide groove 12, two sliders 13 are provided in the slide groove 12, and a switch magnetic seat 14 is provided on the slider 13, with the adsorption surface of the switch magnetic seat 14 facing inward.

[0027] A reinforcing rib 15 is provided between the guide plate 10 and the end plate 11, and the lifting end of the hoist 4 is connected to the reinforcing rib 15.

[0028] The lifting end of the hoist 4 is horizontally connected to the reinforcing rib 15 after passing around the third rotating shaft 8.

[0029] The front side of the base plate 1 is provided with an L-shaped rotating plate 16. The horizontal part of the rotating plate 16 extends backward and has multiple nails 17 at the bottom of the rear end. The vertical part of the rotating plate 16 is rotatably connected to the base plate 1. The first rotating shaft 6 is rotatably connected to the upper rear side of the rotating plate 16 through a corresponding bracket.

[0030] A spring 19 is provided between the rotating plate 16 and the base plate 1. The spring 19 is a tension spring, located between the lower rear side of the rotating plate 16 and the base plate 1. The spring 19 can also be a compression spring, located between the upper end of the rotating plate 16 and the base plate 1. The spring 19 causes the rotating plate 16 to rotate counterclockwise.

[0031] The gantry 3 is located near the front side of the base plate 1, and a support beam 18 is provided between the gantry 3 and the base plate 1.

[0032] Working principle: such as Figure 1 As shown, two switch magnetic seats 14 are placed on both sides of the web of the track 20, and the switch magnetic seats 14 are moved so that the adsorption surface of the switch magnetic seats 14 is in contact with the track 20. The switch magnetic seats 14 are opened so that the switch magnetic seats 14 are firmly attracted to the track 20. The switch magnetic seats 14 are 30T in size, with a single attraction force of 300Kg and a single weight of 4.8Kg. The static friction coefficient between the switch magnetic seats 14 and the track 20 is approximately 1. It takes a pulling force of more than 600kg to separate the two switch magnetic seats 14 from the track 20, which meets the usage requirements.

[0033] By pulling the manual cable (ring) on ​​the hoist 4 in the reverse direction, the hoist 4's sling is disengaged to its longest position, pushing the trolley towards the track installation position (at this time, the sling is not taut; under the action of spring 19, the rotating plate 16 rotates counterclockwise, preventing the anchor bolt 17 from contacting the ground). Pulling the manual cable on the hoist 4 in the forward direction retracts the sling, and the track 20 is dragged towards the destination by the tow device. This process is repeated until the track reaches the destination; the longer the sling, the greater the distance the track 20 moves in one go.

[0034] When the track 20 is dragged, the sling is under tension, causing the first rotating shaft 6 to move backward, overcoming the elastic force of the spring 19, and causing the rotating plate 16 to rotate clockwise. The spikes 17 then drive into the ground, establishing a reliable connection between the base plate 1 and the ground, preventing it from retracting under the reaction force of the track. The heavier the track 20, the deeper the spikes 17 penetrate. After one drag, the rotating plate 16 needs to be manually pushed to lift the spikes 17 off the ground before the tool can be moved.
